N2  - With the advances in radiologic technic of the past few years, tests of gastric function have been more and more neglected in the study of disorders of the stomach despite the fact that it would seem advisable to take advantage of every diagnostic aid in dealing with a department of medicine as difficult as that of digestive disease. The test meal in its various conventional forms has, to some extent, fallen into disrepute—perhaps for good reason—but it is our purpose in this paper to show that carefully standardized studies of gastric function play an essential part in diagnosis and may even lead to a correct understanding of the condition after other methods have failed.CRITERIA OF A SATISFACTORY FUNCTIONAL TEST 
    In testing any physiologic function, certain criteria must be observed if data of comparative value are to be obtained. First of all, the test must be applied under standard conditions.
